For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.

    Building an entire engine just for nitrous - your input needed.

    OK, ive grown tired of trying to put together a custom turbo setup for my F22A4 bottom/F22B1 head engine. Now, I think i just want to build a motor that will PROPERLY handle a good shot of nitrous (150-200?), maybe a F22 whatever, or a H23, something in the lower-dollar ballpark. What will I need to pay close attention to, as in parts that will recieve the most abuse? What will I need to do fuel-wise? Timing wise? Then, what kind of kit will i have to go with? I know I sound like a total n00b, but i do know some basics....I just would rather be safe than sorry. Thanks in advance to all the people that give ideas.

    In terms of lower block choice...all I could tell ya is I've heard the H23 is a fairly solid block. Others can elaborate on that. Definitely some good forged or even billet rods & forged pistons. Not sure what compression ratio is optimal on N20 systems. New head gasket, make sure no leaks maybe even a multi-layered steel one.

    For the nitrous setup, it'll obviously be a wet system or direct port. Therefore, based on ur 150-200 shot goal (dang that's alot) I would suggest high flow fuel pump, fuel pressure regulator, 4 larger injectors instead of doing the add on injectors so you can make sure you're getting even distribution of fuel/N20 mixture to each cylinder. Also, for simplicity sake, AEM makes a fuel rail that's like $125, it has ports for 4 injectors and 4 other ports for N20 & it's higher volume. You would have to purchase 4 new spark plugs specific for your N20 application. Maybe further upgrades to your ignition...others would know more on that.

    You'd definitely need a fuel management system, I couldn't tell ya if a piggy-back or reprogrammin the ECU would be better.

      Yeah, 150-200 IS a lot of nitrous, but its what i plan on building to, if at all possible. I dont want to hear how nutty it is, 'cause I know all about it (just kidding ). OK, so, billet rods and forged pistons are a must, what about sleeving the block, for either engine (F22B1 or H23A)? I know some people do for turbo applications, but I dont know if it is nessecary for nitrous. Compression ratio? Can anyone give me a good one? Head gasket...like just a thicker/stronger one? OK....so....lots of question-asking going on here. Fuel setup: Walbro fuel pump, 440CC DSM injectors, AEM FPR and fuel rail? Then, colder plugs, retarded timing, etc? I plan on running the car with a chipped p28 ECU. Planned ECU Any more suggestions? As far as brands, engine machining, etc? Thanks fellas

        OK, I got the H23 COMPLETE engine today, for the great price of $0.00. Its good to have friends that like you Auto tranny though So, now, the building will begin. What first? Strip down the block? Please point me in the right direction. ALSO......I know that people can make LS/VTEC engines by basically adding a GSR VTEC head to a non-VTEC block, right? So could I add a H22A VTEC head to a H23 non-VTEC block? I think its been done, but my H series knowledge is pretty limited.

          If you would like to know how to build a motor for nitrous you can go to my thread on HS and read about what I have done.
